yes - he's "tied" - the fence is 48" - he could go over it, or get injured trying.... a chain link style would be one thing, but getting a leg caught in the gap between pickets would be most unpleasant.
with the deer and other friends we don't risk it. he's quite used to being on a tether - so he doesn't fight it, fortunately.... he runs to the end - sits/stands/dances - chats with his forest friends. mostly he serenades them - we are informed daily when the deer move through.
huskies don't have a stellar reputation for "nice dog" but the groomer/vet/etc people just love him as he's super friendly. the vet said he's just a clown.
